# Audio_pcm_flac_enc_dec **Repository Path**: linriming/audio_pcm_flac_enc_dec ## Basic Information - **Project Name**: Audio_pcm_flac_enc_dec - **Description**: 使用开源项目LibFLAC来将PCM格式数据和FLAC无损压缩格式进行编解码。 - **Primary Language**: C - **License**: Not specified - **Default Branch**: master - **Homepage**: None - **GVP Project**: No ## Statistics - **Stars**: 1 - **Forks**: 0 - **Created**: 2024-06-11 - **Last Updated**: 2025-04-23 ## Categories & Tags **Categories**: Uncategorized **Tags**: pcm, 16lePCM, FLAC ## README #### 1、移植步骤源码下载地址：[https://github.com/xiph/flac/releases](https://github.com/xiph/flac/releases) ```bash tar xzf flac-1.4.3.tar.gz cd flac-1.4.3/ ./autogen.sh ./configure --prefix=$PWD/_install --enable-static --disable-shared make -j8 make install tree _install/ -h ``` #### 2、demo使用方法 ##### 编译 ```bash $ make clean && make rm -rf pcm2flac flac2pcm out* gcc main_pcm2flac.c -I./include -lFLAC -L./libs -lm -o pcm2flac gcc main_flac2pcm.c -I./include -lFLAC -L./libs -lm -o flac2pcm ``` ##### 编码 ```bash $ ./pcm2flac Usage: ./pcm2flac

Examples: ./pcm2flac ./audio/test_16000_16_1.pcm 16000 16 1 out1.flac ./pcm2flac ./audio/test_44100_16_2.pcm 44100 16 2 out2.flac ``` ##### 解码 ```bash Usage: ./flac2pcm

Examples: ./flac2pcm ./audio/out1.flac out_16000_16_1.pcm ./flac2pcm ./audio/out2.flac out_44100_16_2.pcm ``` #### 3、参考文章 - [FLAC 格式详解_flac格式解析-CSDN博客](https://blog.csdn.net/ffgamelife/article/details/7893747) - [FLAC 格式详解 - 刘文涛 - 博客园](https://www.cnblogs.com/liuwt0911/articles/3730378.html) #### 4、demo使用日志 ##### 编码如果是双声道，那么一个采样点就包含16bit*2channels等于4个字节，单通道就是2个字节（16bit），那么，文件大小/一个采样点的字节数=总的采样点数。另外，从日志里看，这里1帧（frame）是由4096个采样点编码而成，那么我们程序里每次读取1024个采样点传递进去并不是直接进行编码的。 ``` $ ls -l audio/ total 6088 -rw-rw-r-- 1 lin
